Prier’s C-633 Series is a heavy-duty commercial wall hydrant with two unique designs; one with a 360° swivel that allows a simple piping orientation inside a narrow wall and the other which consists of a close-coupled design for straight supply piping applications. Both designs have inlets that will connect to either 3/4” MPT or 1” FPT pipe in tight spaces. The hydrants are key operated, code approved, with flow up to 19 gpm, and a box option that will allow for installation inside a 6” wall. The series is heavy-patterned high-quality solid brass and incorporates a satin nickel-plated finish. The operating stem is manufactured of solid brass. The stem’s threaded ends, triple-seal stopper and worm sleeve are pinned and removable to simplify future maintenance.
